Abrégé
Multi-state switchability is highly desirable in optoelectronic devices. For liquid crystal (LC) based devices, the stability of any configuration is achieved through a balance between imposed interactions and the LC's orientational elasticity. In most cases, the latter acts to resist deformation. By combining surface topography and chemical patterning, provided here are the effects of saddle-splay orientational elasticity, a property that, despite being intrinsic to all LCs, is routinely suppressed. Utilizing theory and continuum elastic calculations, provided here are example conditions for which, even using generic, achiral LC materials, spontaneously broken surface symmetries develop. Also provided are multi-stable devices in which a weak, but directional, applied field switches between spontaneously-polar surface state domains. The disclosed approach is useful in low-field and fast-switching optoelectronic devices, beyond those attainable by current technologies.

IMAGE DATA COMPRESSION AND DECOMPRESSION USING MINIMIZE SIZE MATRIX ALGORITHM
Computer implemented methods of compressing and decompressing image data are described. A discrete cosine (DCT) transformation is applied to each of a plurality of pixel blocks to generate a set of DCT coefficients for each pixel block comprising a DC DCT coefficient and a plurality of AC DCT coefficients. Each set of DCT coefficients is quantised. A DC array is formed from the set of quantised DC DCT coefficients and an AC matrix is formed from the set of quantised AC DCT coefficients. The AC matrix is compressed by eliminating blocks of data having only zero values and forming a reduced AC array from blocks including non-zero values. The reduced AC array is compressed using a key to form a coded AC array. The DC array and coded AC array are arithmetically coded to form arithmetically coded data which is included in a compressed image file. The decompression method is essentially the reverse process.

The probe, in the form of a solution or coating is capable of fluorescing in response to the generation of metal ions at the metal substrate resulting from corrosion processes. The detection solution comprises a binder configured to increase adhesion of the solution when applied to the substrate. Additionally, a method of applying the formulation to the substrate in the form of a spray, particularly an aerosol, is disclosed. Corrosion of the metal substrate is identified by irradiating the coated substrate with ultra violet light and observing resulting fluorescence.
An organic-inorganic hybrid (ormosil) coating and method of preparing the same is provided. The method of coating preparation involves sol-gel processing techniques in which a first layer is formed from deposition of a sol comprising a curing agent followed by application of a second sol comprising at least one ormosil or ormosil hybrid onto the first layer. Dopant compounds or materials may be added to the curing agent sol to effect the chemical and/or mechanical properties of the coating. A thick and dense anticorrosion coating is provided.
A PVD coating is disclosed, and in particular a nanoscale multilayer superlattice PVD coating comprising high hardness, a low friction coefficient and increased chemical inertness. The multilayer coating comprises a repeating bilayer represented by (Vx Me(i-x)) Cy N(i-y) / (Mez V(1-z)) Cy N(i-y) where 0.1 ≤ x ≤ 0.9; 0.01 ឬ y ឬ 0.99 and 0.1 ≤ z ≤0.9 and Me is a substantially pure metal or a metal alloy. The composition of the coating through the layers alternates from layer to layer according to a V-rich layer and a Me-rich layer modulated sequence. Vanadium is incorporated within the layer composition and has been found to act as a lubricating agent during sliding wear. Carbon, also incorporated within the coating, serves to further stabilise the friction coefficient thereby increasing the chemical inertness between cutting tool and workpiece material.
